E-UTRAN Node B, also known as Evolved Node B (abbreviated as eNodeB or eNB), is the element in

Traditionally, a Node B has minimum functionality, and is controlled by a Radio Network Controller (RNC). However, with an eNB, there is no separate controller element. This simplifies the architecture and allows lower response times.

Differences between an evolved Node B and a Node B

Air interface

eNB uses the E-UTRA protocols

Control functionality

eNB embeds its own control functionality, rather than using a RNC (Radio Network Controller) as does a Node B.

Network interfaces

eNB interfaces with the
